Radio Frequency Tests on Antenna Insulators

After analyzing the design considerations for high voltage radio frequency continuous wave antenna insulators, there are given data on the heating, losses, and flashover points of a number of sizes and forms of porcelain rod insulators, both dry and wet. The effect of rain shields, electro-static strain shields, and "breathers" on the behavior of the insulators is discussed. The voltage distribution across insulators in series was determined. Its effects on design are given. A study of visual corona point on conductors at radio frequencies is included.
